To @ZZ whom, it may concern:

Be it known that I, VILBUR F. GILBERT, a citizen of the United States of America, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Bolt- Actuators, of which the following is a speciication.

The object of my invention is to provide a device of the class specified having features of novelty and advantage.

Referring to the drawings, Figure lis a front view of the device. Fig. 2 is a sectional view on the line 2 2 of Fig. l.

This device comprises a slotted face-plate on the rear surface of which locking-notches are formed. A spring whose ends are adapted to coperate with said locking-notches is carried by the knob-shank, which works in the slot in the plate. `On the inner end of the knob-shank a socket is formed to receive the bolt.

In the specific form of the device shown in the drawings there is a face-plate c, slotted as at I). A back plate c, having grooves c c at its ends, is secured to the rear surface of the face-plate, having a slot c2 located between the grooved ends of said plate. The shank 0l' of the knob Z passes through these slots and is secured to a flat spring e, which extends on each side of said shank in such a manner that (No model.)

at either limit of the movement of the bolt one end of the spring is in engagement With one of the grooves. The ends of the spring are formed with projecting ribs e', which interlock with the grooves in the back plate. Secured to the knob-shank back of the spring is a socket member f,vvhich receives the bolt g.

I claim as my inventionl. A bolt-actuator comprising a slotted face-plate having notches on its rear surface,

a knob having a shank working in said slot, a

spring secured to the said shank and adapted. to interlock with the notches on the rear surface of the face-plate, and a bolt carried by said knob-shank.
